Use of open source DTrace to identiy software bottlenecks and dynamically adjust resources
Speaker: Bryan Cantrill, Sun Microsystems Incorporated

Venue: 78-420
Host: Prof Paul Bailes
Abstract:DTrace helps you identify application bottlenecks and dynamically
adjust resources in minutes, not days. DTrace can non-invasively
observe a running operating system to gain insights into performance
and availability, all with no measurable impact to the system
stability. DTrace is part of Sun's Solaris 10 which has been
released into the Open Source Community and is also available for
x64 platforms as well as SPARC.
